Project: Modeling Energy Changes

create a model to show how energy changes in a chemical reaction

A Chemical reaction involves changes in energy in the form of absorbtion and release of heat due to the formation and breakdown of chemical bonds. A chemical reaction is categoried as endothermic reaction in which heat energy is take in or absorbed and exothermic reaction in which energy is released.

A model can be created by following below details:

Take a beaker and put 10 milliliters of vinegar in it. Place a thermometer in the beaker and measure the initial temperature. Then add half teaspoon of baking soda, that results into decreasing in the temperature.

So, the decrease in temperature shows it is an endothermic reaction in which heat energy is absorbed.
